Don't toss that broken piece of plastic!

I know, I've been away from our forum for a very long time....I have been waylaid by my two other motorcycles, a '08 Suzuki DR650 and a new to me Honda NX 250 from 1988. It is testament to my '83 R65LS, Little Red Baron's mechanical prowess that I haven't needed help for awhile for him. Anyway the point today is I want to share my latest find: a method to fix cracks and broken tabs on the plastics used on our bikes.
From internet info: mix up some Lego pieces with some acetone! LEGO is made of ABS as are our bikes' plastic bits. Acetone melts the ABS piece and welds the repair. The mix goes through a series of thicknesses from a liquid, through a slurry, pancake mix, putty/clay back to solid. Useful at all stages for some fix! You can cast a broken tab and 'weld' it on or fill a gouge with the liquid stage and it hardens in about 10 minutes or so depending on thickness. On my R65LS I am experimenting with the mix to re-create a broken tab on the back of the "always broken" battery cover. The hardened piece of recreated ABS can be filled for drilled, filled for shape, sanded and painted. One can purchase kits that do the same, maybe a bit better, but these are expensive. This method, if you want ABS in black, takes one trip to the plumbing section for a piece of ABS pipe! For white which I needed for the Honda NX250, I ordered LEGO from the main factory...$.09 per piece.....but I am sure there is something white out there cheap[ that I haven't ID'd yet.
Maybe someone can help here? Anyway, I hope this idea can help someone as those replacement plastics are horrendously expensive! There is probably few LS's that still have all the tabs on the black nacelle of the front 1/4 fairing!

1983 R65LS - LRB still my favourite!  '08 Suzuki DR650 Cyclops stored beside '04 DR200 "Toodles". Little brother Big brother with a good German warden to suggest how it should be...

This is a great tip,  Sue.  Thank you.  I am going to play with this on a side cover tab and likely make a mess but there is hope.

That is a great tip. I know I have broken plastic that I can't wait to try and fix.
